How do you measure 1/4th of an egg? 

This seems silly, but the only way to measure 1/4th of an egg is to mix it and then separate 1/4th of it. 

Would we make this TikTok Fudgy Brownie in a Mug again? 

The fudgy texture was good and was delicious with the vanilla ice cream.

COOK TIME: I’d recommend trying this out – maybe 35 seconds vs. 45. Of course, each microwave differs.

Expert Mug Brownie Recipe Tips

While you should always use a microwave-safe mug (and there are plenty with golden letters or paint that are not safe for microwaves, so be aware), they still get super hot.

I find that any time a mug sits in the microwave for about 1 minute, it results in a hot cup. Be aware you may need oven mits to remove. 

Use a ramekin instead of a mug.

Do not let fun toppings or mix-ins escape you! Try swirling in Nutella, extra chocolate chips, or Peanut butter for a melty fudgy treat. 

I want to be clear that mug dessert recipes are not the same as breaking out the baking powder and cooking a full-on 1-hour dessert.

These gooey mug recipes are meant to satisfy chocolate cravings and are fun to enjoy, but they do not have the same texture or taste as their longer counterparts. This sweet treat is the perfect size with simple ingredients to enjoy a brownie anytime.

This fudgey brownie recipe is just as good! Try the 1-minute Molten Lava Mug Cake from TikTok for another chocolate mug cake recipe.

Perhaps the original viral dessert recipe, this Oreo Mug Cake is a great way to take Oreo Cookies into a 5-minute brownie as well. 

Our no-fail easy fudge recipe is one of the highest-rated holiday recipes on the site.
